Osisko Development hits 13.19 g/t Au at 596 m and 28.90 g/t at 718 m depth
ODV•Osisko Development completed 8,971 m of surface drilling at its Cariboo Gold Project, with 65% of metres outside the current deposit footprint and intercepts including 13.19 g/t Au over 3.60 m at 596 m depth and 28.90 g/t Au over 0.50 m at 718 m depth. Five rigs are testing down to 800 m.
1. Exploration Program Overview
Osisko Development deployed five surface drill rigs under an 8,971 m program at Cariboo Gold Project between December 2025 and April 2026. Approximately 65% of metres tested areas outside the existing mineral resource footprint, targeting under-drilled gap zones and depths up to 800 m vertical.
2. Key Drilling Results
Highlight intercepts include 13.19 g/t Au over 3.60 m at 596 m depth and 28.90 g/t Au over 0.50 m at 718 m depth, alongside 6.40 g/t Au over 6.30 m at 326 m and 6.17 g/t Au over 7.10 m at 517 m. Additional high-grade hits featured 42.42 g/t Au over 1.50 m at 111 m and 13.83 g/t Au over 1.55 m at 277 m depth.
3. Resource Growth Potential
Results confirm high-grade mineralization beyond the current 350 m average footprint, reinforcing potential for resource growth at depth and within gap zones. Ongoing drilling aims to expand the deposit within the Project’s existing permitted area.
